SCHEMATIC ILLUSTRATING THE PROJECT IS ADDED TO GIT
SUMMARY
The main goal of this project was to test different ways to send data using MQTT. This project uses the public broker iot.eclipse.org.
The system logs, displays and uploads Hall sensor and temperature data.
The main goal of this task is to demonstrate ESP and Raspberry communication with MQTT.
The project includes: ESP32, Raspberry Pi, integrated LED in ESP32, integrated hall sensor in ESP32, Wemos D1 Mini, temperature sensor,
LCD, Eclipse public broker iot.eclipse.org, ThingSpeak cloud for visualization and system logs. The code for this project are written in C, Python and Arduino.
Hall sensor node
This is Sparkfun ESP32 Thing with internal Hall sensor. Since the previous lab task (Mario ESP32 task) was written with Eclipse in C, it was decided
